Application filed November 14, 1919. p Serialv No. 338,052.

To all whom it may concern: n

Be it'known that I, HENRY PAAR, a citizen of'the United States, residingat Canton, in the county of Stark and State of Ohio, have invented a newand useful Cushion-Horseshoe, of which the following is a specification.

This invention relates to horseshoes and more particularly towhat mightbe termed spring-tread or spring-heel shoes, provided with removablecushioned c'alks, and de vised with the object of diminishing concussionto, and preventing the animal accidentally pulling olf, the calli incase of meeting with an obstruction.

The objects of the invention are to construct a horseshoe with removablecalks whereby all of the advantages of elasticity of tread, andtheconsequent avoidance of concussion due to hard pavements or roads andthe accidental displacement of the call; are obtained, withoutdisadvantage as to the durability of the shoe or injurious effects uponthe animals hoof; and the invention consists in providing the shoe witha pair of removable cushion calks provided with removable andcompressible cushions, which can be readily applied to horseshoes now ingeneral use.

Further objects are the provision of a removable and replaceable cushioncalk for horseshoes which is simple, strong and durable in construction,efficient in use, easily and readily applied to the heel portion of ausual construction of horseshoe, and ineX- pensive to manufacture.

TWith these objects in view, the invention consists in the novelconstruction and arrangement of parts hereinafter described, illustratedin the accompanying drawings, and particularly pointed out in theappended claims, itV being understood that various changes in the form,proportions, size, and minor details of construction may be made withinthe scope of the appended claims, without departing from the spirit orsacrificing any of the advantages of the invention.

Figure 1V is a bottom plan view of a horseshoe embodying the invention;

Fig. 2 is a longitudinal sectional view through the horseshoe;

Fig. 3 is an enlarged longitudinal sectional view through the cushionedcalli;

Fig. 4 is a--detail perspective view of the calli; and

Fig. 5 is a similar view of the cushion.

A practicalembodiment of the invention is disclosed in the accompanyingdrawings,

forming a part of'this specification, inA

which similar numerals of reference indicate corresponding partsithroughout the several views.

The shoe is indicated by the numeral 1, and may be of any usualandwell-known construction, preferably provided at the toe portion with theintegral calk y2. A ypair of apertures 3, 3a is located through eachheel portion of the shoe, these apertures being spaced longitudinallyupon the shoe as shownV and extending vertically through the shoe. Withthey exception of the provisions of these apertures the shoe is of knownconstruction and is not otherwise changed eX- cept that it is providedwith the tapped bores 4, one of said bores being provided in each heelportion.

A cushion y5 of rubber or other resilient or elastic material is mountedupon the tread portion of each heel of the shoe, constituting acompressible cushion adapted to diminish concussion upon the animal whenthe shoe is worn and providing an elastic tread. The cushion isprovidedwith the vertical end grooves 6 adapted to aline with the apertures 3,3a, and with a boss 7 provided with a vertical aperture 8 adapted toaline with the tapped bore 4.

A calk 9 is mounted against each of theI cushions 5 and provided withthe spaced studs 10, 10a arranged to be accommodated within the grooves6 and to be slidably received within the apertures 3, 3at respectively.vEach calk is preferably provided upon its inner face with a verticaldepression 11 and with an ear 12 at the lower extremity of saiddepression, said ear having l a countersunk aperture 13 thereinregistering with the aperture 8 in the cushion and arranged to seat thehead of the screw 14 which is located through the aperture 8 in thecushion and engages the tapped bore 4 outward movement of the calk withreference to the shoe, obviating any lost motion, but the inwardmovement of the calk is limited only by the compression of the cushion5, a resilient or elastic tread being thus assured and the concussion tothe animal being appreciably diminished.

The lower or tread face of the calk is preferably of greater height atits rear end and tapered slightly forward, and is generally providedwith the serrated tread face l5 to aid the animal in traveling over icyor slippery roads or pavings.

From the foregoing description it will be evident that a simple andefficient cushioned calk is produced which may be quickly and readilyapplied to the shoe, means be ing provided for preventing the accidentaldisplacement of the calk by the animal. It should also be noted that thecalk is applicable to any usual construction of shoe, this in itselfbeing a material advantage as no special form of shoe is necessary incarrying out the invention. Furthermore it will be evident that theelasticity of the tread obtained by the construction of shoe abovedescribed has the effect of not only diminishing concussion, but ofincreasing the durability of the shoe, and the cushions besidesaffording elasticity of tread act also as insulators to prevent thetransmission to the hoof of the heat generated by friction or acquiredby contact with the hot pavements or roads.

I claim: e

1. A horseshoe having each of its heels provided with a pair of spacedapertures, a cushion mounted against each heel between said aperturesand having vertical grooves in its ends registering with the apertures,a calk engaging each cushion7 studs upon the calk engaging the groovesin the cushion and extending into the apertures, an ear upon the calk,and a screw located through the ear and through the shoe.

2. A horseshoe having each of its heels provided with a pair of spacedapertures, a cushion mounted against each heel between the apertures andhaving vertical grooves in its ends registering with the apertures, aboss upon the cushion provided with a vertical bore, a calli engagingeach cushion, studs upon the calk engaging the grooves and extendinginto the apertures, a perforated ear upon the callr registering with theboss on the cushion, and a screw located through said ear and boss andthrough the shoe.

In testimony that I claim the above I have hereunto subscribed my name.

HENRY PAAR;
